TECHNICAL FIELD

The present disclosure preferably, but without limitation, generally pertains to sealed packages, and more specifically pertains pre-Tillable sterile packages and method of filling thereof.

BACKGROUND

Medications, and in particular injectable medications, need to be stored sterile in aseptic commercial packages until the time of use. Some medications are stored in pre-filled single dose dispensing devices such as pre-filled syringes, for example, the pre-filled syringes from Vetter (Ravensburg, Germany). Yet most of injectable medication are stored in aseptic packages and are transferred to a dispensing device (i.e., drug delivery device) shortly before use. The term dispensing device include without limitation hypodermic syringes, micro needle syringes, micropumps, autoinjectors, jet injectors, topical dispensers, intradermal delivery devices, patch pumps, auricular dispensers, oral dispensers, eye droppers, autoinjectors, infusers, prefillable syringes, pre-filled syringes, cartridges for pen injectors, cartridges for auto-injectors, or any other type of drug delivery device.

Several aseptic packages for storing injectable medications are commercially available. Perhaps the most common aseptic package for injectable products is glass vials. Some medications are stored in separate vials and are mixed just prior to use. Often this is done to improve the medication's stability or to extend the medication's shelf life. In one example, the medication is a vaccine that is kept dry in one vial to extend the vaccine thermo stability, and a companion vial stores a diluent that is dispensed to the vaccine vial via a syringe and needle prior to injection. In another example, the medication is a vaccine where one vial stores the formulated antigen and the second vial stores an adjuvant.

Several existing products include a flexible package made from film or foils in which a product can be stored in an aseptic manner until the time of use. Some of these products further include a dispensing port communicating with the product in the dispensing package. In some cases, a rupturable barrier is presented between the port and the product to enhance the integrity of the package until the time of use. These flexible packages may comprise at least two product compartments that are mergeable prior to use to allow the substances from the different compartments to mix and form the dispensable product. In some cases, these packages are made from a film or a foil (together referred to as webs or web walls) where a first web wall is sealed to a second web wall to define the boundaries of a product compartment. These packages are sometimes referred to as bags, blisters, pouches or sachets.

Packages for drugs, pharmaceutical agents or other beneficial agents are sometimes referred to as containers, primary containers, and container-closure systems. Packages are typically filled using a filling system. In the broader sense, fillings systems are configured to receive a package empty, fill the package, seal the package, and in some instances further arrange the package in a secondary package. At the filling step, the package is filled with one or more materials that are typically measured to receive a precise dose in the package. For liquids and other flowable substances, metering pumps are used to measure a precise dose into the package. Weighing the package is another common method of measuring a dose into a package. For powders, solids, and non-fluidic substances, filling systems may incorporate a volumetric transfer instrument or an acoustic measuring system to facilitate filling a precisely measured dose into a package.

In most cases, the package is received at the filling system open, or it is open during the filling step such that the interior of the package is exposed to the surrounding environment. For pharmaceutical products, and particularly for sterile products that are administered parenteral such as by intravenous (IV) infusion and injection, rigorous measures are taken to prevent contamination, foreign biologic matter, and foreign particulates from entering into the container. In several cases, the pharmaceutical ingredient cannot be sterilized after filling, hence the filling process is executed using pre-sterilized packages in a controlled clean environment. Several types of filling systems incorporate the steps of receiving open packages, washing, drying, sterilizing, and inspecting the packages prior to filling. After filling, the packages are sealed, still in the controlled environment, by joining the walls of the package or by introducing a closure to the package.

The filling process described above requires a sophisticated filling system that involves very high capital equipment expenditures and operation costs to the pharmaceutical filling company. These systems typically occupy significant and expensive clean-room space at the filling site while having a limited production throughput.

Some of the foregoing shortfalls have been partially addressed by several packaging suppliers. The Stevanato Group, Nuovo Ompi division (Padua, Italy) provides pre-fillable containers that have been pre-washed, sterilized and inspected, in sterile nesting trays, hence avoiding some of the upstream steps of preparation steps prior to filling.

Aseptic Technologies S.A. (Les Isnes, Belgium), and Medinstill (New Milford, Conn.) provide a pre-sterilized, sealed containers, particularly vials, and filling systems for accessing the container by piercing a rubber stopper with a piercing member, in a form of a needle, by which the package is filled; and resealing the access region after the package has been filled and the piercing member has been removed. Using such methods, these containers and filling systems avoid a number of upstream preparations typically required as filling steps at the filling site. Accessing the package for filling in a fluid-tight fashion, while the package is otherwise closed, reduces the risk of exposure of the interior of the package to contaminants, and can potentially reduce the controlled environment requirements during filling. The foregoing technologies have the potential of reducing capital equipment and filling operation complexities and costs while reducing contamination risks. However, such filling systems would benefit from further simplification and minimization of downstream operations after filling.

One limitation that is common to the foregoing filling systems is the challenge to scale up production on a single line because of the filling metering systems. Whether the filled dose requires weighing or metering with a pump, manufacturing scale up require more measuring systems installed and operated on a single line, thereby resulting in more expensive, larger, and less reliable filling systems. Therefore, filling metering systems that allow manufacturing scale up without compromising reliability or increasing the system size and costs would be an important advance in this field.

In some package applications, another limitation is the presence of air bubbles in the package after filling (i.e., sometimes referred to as headspace). Head space, and particularly inconsistency of head space, in a package may affect the accuracy of the dose received by a patient. This is particularly true with cartridges for pen injectors and auto injectors with limited options for removing air bubbles prior to injection, and where air may be injected to the patient in place of the actual drug. Another problem with headspace in the package is that some pharmaceutical products are sensitive to interaction with air, hence the presence of air bubbles may adversely affect the drug stability and efficacy.

The packages and packaging limitation listed above are valid in other industries beside the pharmaceutical industry, including, for example, medical device packaging, food packaging, cosmetic packaging, and nutraceuticals packaging.

DETAILED DESCRIPTION

FIGS. 1a-1b show an example package 10 in accordance with the present disclosure. The package 10 includes first and second compartments 20 a, 20 b, first and second filling chambers 22 a, 22 b, first and second filling channels 24 a, 22 b, and first and second layers or walls 26, 28. The package 10 may also include at least first and second frangible seal portions 30, 32, first and second access regions 34 a, 34 b, and a fitment 36.

FIG. 1c shows the first layer 26 as a pre-formed flexible wall of the package 10. The first layer 26 includes first and second compartment cavities 40 a, 40 b, which when later sealed using the second layer 28 form the first and second compartments 20 a, 40 b. The first compartment 20 a receives a first constituent (e.g., a beneficial agent or constituent of a beneficial agent). The second compartment 20 b receives a second constituent (e.g., a beneficial agent or constituent of a beneficial agent) which is typically different from the first constituent. The first layer 26 also includes an uninterrupted area at a peripheral edge of the first compartment cavity 40 a, which is spaced between the first and second compartment cavities 40 a, 40 b, that subsequently becomes the first frangible seal portion 30. A second uninterrupted area at the peripheral edge of the second compartment cavity 40 b, which is spaced between the first compartment cavity 40 b and a fitment cavity 46, subsequently defines the second frangible seal portion 32.

The first and second layers 26, 28 may have flexible characteristics and may be referenced as flexible walls of the package 10. A flexible wall may include a portion of the package that is deformable by pressure of force to substantially affect a configuration of the package and accuracy of a volume of at least one of the first and second compartment 20 a, 20 b.

Typically, the first compartment 20 a defined by the first compartment cavity 40 a receives a liquid. The second compartment 20 b defined by the second compartment cavity 40 b typically receives a non-fluidic material or a poorly flowing material such as, for example, powder, compressed or agglomerated powder, granules, pellets, solid, tablets, capsules, slurries, paste, hibiscus fluid, emulsions, or a combination thereof. The substance received in the second compartment 20 b is filled into the second compartment 20 b by an appropriate filling system that provides the type of material that needs to be filled. The second compartment 20 b may also be filled with water or other viscosity fluid. In some examples, it may be challenging to completely fill the second compartment 20 b with water or aqueous solution due to surface tension and other properties of the fluid, which may make it challenging to maintain the fluid in the compartment as the compartment is being sealed.

Another challenge related to filling the package 10 is that liquid filling is a relatively slow manufacturing process for a number of factors, one of which is avoiding foaming or bubble formation as the liquid is filling at least one of the first and second compartments 20 a, 20 b.

The substance used to fill the second compartment 20 b may be a loose powder or another form of disbursable dry substance, which may be challenging for filling a second compartment 20 b.

The first compartment 20 a typically provides another arrangement for efficiently filling a low viscosity fluid to substantially fill the first compartment 20 a. In one example, the package 10 includes the first and second filling chambers 22 a, 22 b provided in flow communication with the first compartment 20 a via the first and second filling channels 24 a, 24 b, respectively. Portions of the first and second filling chambers 22 a, 22 b may be pre-formed in a first layer 26 as first and second chamber cavities 42 a, 42 b. Portions of the first and second filling channels 24 a, 24 b may be pre-formed in the first layer 26 as first and second channel cavities 44 a, 44 b. The term pre-formed in the context of this figure may be at least one of thermoforming, vacuum forming, cold forming, plug assign forming and pressure forming, however similar package configurations may be made from materials and processes other than web material and processing thereof. Hence in some embodiments at least a portion of at least one of the cavities 40 a, 40 b, 42 a, 42 b, 44 a, 44 b, may by pre-formed using injection molding, blow molding, injection blow molding, stamping, machining, deposition and etching. The first filling chamber 22 a may be referred to as an inlet filling chamber. The second filling chamber 22 b may be referred to as an outlet, exhaust, or evacuation filling chamber.

The first filling channel 24 a may be referred to as an inlet channel or passageway, or a first pre-formed filling channel. The second filling channel 24 b may be referred to as an outlet passageway, or a channel, or a second pre-formed filling channel. The first and second filling channels 24 a, 24 b may be collectively referred to as Tillable channels, filling channels, or passageways used to fill the first and second compartments 20 a, 20 b.

The first and second layers 26, 28 may be portions of a web that have features of the package 10 formed therein. It may be understood by those of skill in the art that in a normal manufacturing process an array of details for multiple cartridges may be formed in a large spread of the first layer 26 and may be handled simultaneously at subsequent forming and filling steps. The package 10, or any portion thereof (e.g., the first or second layers 26, 28) may comprise a blister package construction that defines pre-formed cavities such as the first and second compartment cavities 40 a, 40 b. The first layer 26 may be pre-formed from a flat web by one or more of the processes including, for example, thermo forming, cold forming, vacuum forming, pressure forming, plug assist forming, or pre-forming from non-web raw material such as by injection molding, blow molding, injection-blow molding, blow-fill-seal, blow-fill-insert-seal, or other methods known in the art. In some embodiments at least one of the first compartment 20 a, a channel, 24 a, 24 b, and a chamber 22 a, 22 b is not performed without affecting the generality of this disclosure.

FIG. 1d is a close-up view of the first filling chamber 22 a and first filling channel 24 a shown in FIG. 1a prior to sealing the package 10. FIG. 1e is a close-up view of the package 10 after being sealed along the first filling channel 24 a. The second filling channel 24 b is typically also sealed. The package 10 may be sealed at other locations such as, for example, at the first and second filling chambers 22 a, 22 b, at the first compartment 40 (e.g., adjacent to an inlet of the first and second filling channels 24 a, 24 b), or at a location overlapping any combination of the filling chambers, filling channels, and first compartment. Sealing the package may comprise deforming (or pinching) at least one portion of the package to bring the first wall 26 and second wall of the package 28 into contact than applying heat to cause the walls to join is a sealed fashion.

FIG. 1f is a bottom perspective view of the package 10 after a portion of the package has been removed. FIG. 1f shows a subsequent step of the manufacturing process of the package 10. After the first and second compartments 20 a, 20 b have been filled, the first and second layers 26, 28 are hermetically sealed to provide a permanent seal region 38 around a periphery of the package 10 as shown in FIGS. 2a-2c and first and second frangible seal portions 30, 32 positioned between the first and second compartments 20 a, 20 b and between the second compartment 20 b and the fitment 36, respectively (see FIGS. 2a-2c ). In one arrangement, an adhesive is used to secure the first and second layers 26, 28 together to provide a controllable peeling (adhesion) force where a lower sealing temperature (for example, about 300° F.) results in a peelable adhesion (“frangible seal”) and a higher sealing temperature (for example, about 420° F.) results in a permanent, non-peelable adhesion. In one arrangement, the frangible seal peeling force is about 1000 g/in², and the permanent seal is greater than about 1600 g/in².

In one example, the first sealing step provides adhering substantially all of the uninterrupted surface of the first layer 26 to the second layer 28 (e.g., extending around substantially an entire circumference of the first and second compartments 20 a, 20 b with the exception of the first and second filling chambers 22 a, 22 b and the first and second frangible seal portions 30, 32). The first and second filling channels 24 a, 24 b remain open and unsealed to permit fluid communication between the first and second compartments 20 a, 20 b and the first and second filling chambers 22 a, 22 b. With the first and second layers 26, 28 now attached to each other, flow communication is provided between the first compartment 20 a and the first and second filling chambers 22 a, 22 b via the first and second filling channels 24 a, 24 b, which are formed between the first and second layers 26, 28. Access regions are defined in the second wall 28 in front of the first and second chambers 22 a and 22 b

The second layer 28 may include first and second access regions 34 a, 34 b in the access regions, as shown in FIGS. 1b and 2b . The first and second access regions 34 a, 34 b may be formed concurrently with accessing the first and second filling chambers 22 a, 22 b during filling. The first and second access regions 34 a, 34 b may be formed using any one of the means known in the art such as, for example, punching, die cutting, and laser cutting, and piercing with a piercing member or a filling member. In one example, the second layer 22 is pierced by a filling device during a filling step when filling the first compartment 20 a. In another arrangement, the first compartment 20 a is filled with a first substance through the first access region 34 a while the second access region 34 b allows for evacuation of gases from the first compartment 20 a during filling. A filling source may be associated with at least one of the first and second access regions 34 a, 34 b during the filling process to facilitate the introduction of a substance to the first compartment 20 a, and drawing the gases through the second filling chamber 22 b. At least one of the first and second access regions 34 a, 34 b and second filling channel 24 b may be sized to prevent the substance from reaching the second access region 34 b. In one arrangement the filling device includes a needle or a tube that is formed to reach into the first filling channel 24 a. The gases drawn through the first or second filling chamber 22 a, 22 b or the first and second filling channels 24 a, 24 b may be connected to an exhaust line (not shown) that draws the gases away from the package 10. One of the first and second filling chambers 22 a, 22 b through which gas is evacuated may be referred to as a gas evacuation chamber. The gas evacuation characteristics achieved by the present designs are not known to exist in the prior art because prior art designs are typically not filling a pre-sealed package that maintains an aseptic environment prior to, during and after filling. The challenges associated with removing gas from an unsealed package are different, and in many scenarios less complicated than gas evacuation from a pre-sealed package in which an aseptic environment is maintained.

In at least one example, the filling device (e.g., device 102 shown in FIGS. 3a-3f ) may include a cylindrical filling tube with a diameter greater than that of the first or second access region 34 a, 34 b within which the tube is inserted. An interface between the filling device (e.g., a cylindrical filling tube 104 shown in FIGS. 3a-3f ) and the package 10 may provide a tight fit with a fluid-tight seal when introduced through one of the first and second access regions 34 a, 34 b. In one arrangement, the first and second access regions 34 a, 34 b are formed during the filling step by a sharp object such as a hollow needle or other piercing element of the filling device that pierces through the second layer 28 and into one of the first and second filling chambers 22 a, 22 b in a fluid-tight manner. The sharp filling object may comprise a tube (e.g., a capillary tube) that is connected in fluid communication with a first constituent or beneficial agent. The second layer 28 may form a fluid-tight seal with the tube while the tube is positioned in flow communication with one of the first and second filling chambers 22 a, 22 b.

This last arrangement may be particularly beneficial as the package 10 is hermetically sealed prior to the introduction of the constituent or beneficial agent, which can be performed on a different portion of the manufacturing line or on a different line. The packages 10 may be stacked between the sealing step and the filling step. In one arrangement, a rubber or semi-rigid sealing member is disposed within at least one of the first and second filling chambers 22 a, 22 b, thereby forming an interface with the filling device to facilitate the sealing of the filling members coupled to the package 10. In at least one example, the cross-sectional shape and size of the first and second filling channels 24 a, 24 b may be sufficiently small to prevent the substance filled into the first compartment 20 a from returning out through the first and second filling channels 24 a, 24 b due to surface tension or particle size of the substance.

In one arrangement, a check valve is disposed in at least one of the first and second filling chambers 22 a, 22 b to control the flow of a substance into the first compartment 20 a. A semi-permeable object may be disposed in at least one of the first and second filling chambers 22 a, 22 b and the first and second filling channels 24 a, 24 b to allow gases to escape during filling and prevent the substance from leaving the first compartment 20 a by backflow. In one arrangement, the flow evacuating the first compartment 20 a during filling is monitored and filling is discontinued when the evacuated fluid switches from gas to the filling substance. A sensor may be positioned in or adjacent to one of the first and second filling channels 24 a, 24 b or the filling chambers 22 a, 22 b, for detecting presence of the substance being filled into the first compartment 20 a. The sensor may indicate that the first compartment 20 a is filled. The sensor may comprise electrodes disposed on the first or second layer 26, 28, in the layers or between the layers 26, 28. The electrodes and associated sensing circuitry may be configured to sense conductivity of the fluid in the second or evacuating filling chamber 22 b, or change in capacitance of the media in a channel or a chamber. An example sensor arrangement is shown in FIGS. 24a-24c and described below.

The first filling channel 24 a may be configured to direct the substance entering the first compartment 20 b to move along the second layer 28 in a way that limits jetting that may result in undesirable bubbles or foaming being formed in the substance filling the first compartment 20 a. A dedicated flow deflector may be disposed in one of the first and second filling channels 24 a, 24 b or in one of the first and second filling chambers 22 a, 22 b to facilitate the gliding of the filled substance on the wall of the second layer 28.

In one arrangement the package 10 is molded as a single body to the configuration shown in FIGS. 1a-1b by, for example, blow molding or gas assist molding.

The package 10 may be sealed after being filled by sealing closed the first and second filling channels 24 a, 24 b from the open construction of FIGS. 1a-1d to the closed or sealed arrangement of FIGS. 1e and 1f . The first and second filling channels 24 a, 24 b may be changed from the open construction of FIGS. 1a and 1 d to the closed or sealed arrangement of FIGS. 1e and 1f . The first and second filling channels 24 a, 24 b may be depressed and welded to completely seal the substance within the first compartment 20 a. The sealing temperature used to seal closed the first and second filling channels 24 a, 24 b may be higher than the temperature used to form the first and second frangible seal portions 30, 32, thereby avoiding rupture of the first and second filling channels 24 a, 24 b (hereafter sometimes referred to as permanent seal verses frangible seal). In one arrangement, this sealing step is further applied to the circumference of the package 10 to create the permanent seal 38 described above to at least some of the areas where the frangible seal is unwanted.

A sealable insert (e.g., insert 150 shown in FIG. 4) may be disposed in the first and second filling channels 24 a, 24 b to facilitate sealing of the channels. The sealable insert may comprise of material with a lower melting temperature than the first and second layers 26, 28. The material of the sealable insert may be adherable to the surfaces of the first and second layers 26, 28 that form the first and second filling channels 24 a, 24 b to enhance the seal provided within the first and second filling channels 24 a, 24 b during the sealing step. A sealable insert may be disposed in at least one of the first and second filling channels 24 a, 24 b and in at least one of the first and second filling chambers 22 a, 22 b to provide at least a portion of a flow control device. The flow control device may be one of, for example, a valve (e.g., an isolation valve or check valve), a flow or pressure regulator, a flow or pressure restrictor, or a flow deflector.

After the package 10 is sealed to seal closed the first compartment 20 a with the constituent or beneficial agent retained therein, the package 10 may be trimmed. FIG. 1f shows the package 10 trimmed by methods known in the art such as, for example, punching, ruler steel cutting, laser cutting, etc. At least the first and second filling chambers 22 a, 22 b may be removed from the package 10 during the trimming step. Additional portions of the first and second layers 26, 28 may be trimmed to reduce an outer profile of the package 10. The package 10 may be trimmed along the sealed portion of the first and second filling channels 24 a, 24 b.

FIG. 1g shows another example package 10 a that does not include the fitment 36 or the fitment cavity 46 formed in the first layer 26. The package 10 a has been filled, sealed, and trimmed to provide the shape shown in FIG. 1 g.

It should be understood to those of skill in the art that the order of manufacturing steps disclosed above may be rearranged in whole or in part to best suit a particular design, application, and applicable manufacturing equipment. It should also be understood to those of skill in the art that additional manufacturing steps may be performed prior to, in between, and after the steps described with reference to FIGS. 1a -1 f.

The fitment 36 may be secured to (e.g., welded) and positioned between the first and second layers 26, 28. The fitment 36 may be secured to the package 10 prior to or during the step of forming the first and second frangible seal portions 30, 32 or during the step of forming the permanent seal 38. The fitment 36 may be secured to the package 10 in any subsequent step by one of the fitment connecting methods known in the art including, for example, heat stake welding, impulse welding, vibration, ultrasonic, RF welding, and light beam welding.

FIG. 2a shows a first welding step of securing the first and second layers 26, 28 together to form the package 10. The seal pattern may completely circumscribe the first and second compartments 20 a, 20 b, the first and second filling chambers 22 a, 22 b, and the first and second filling channels 24 a, 24 b. In this first welding step, the welding is provided with a frangible seal type connection. The subsequent location of the first and second filling ports 34 a, 34 b may be marked so that the first and second filling ports 34 a, 34 b may be formed at a later manufacturing step (e.g., see FIG. 2b ). The first welding step may provide a hermetic seal that hermetically seals the first and second compartments 20 a, 20 b, the first and second filling chambers 22 a, 22 b, and the first and second filling channels 24 a, 24 b. FIG. 2b shows the package 10 after the access area has been penetrated by a piercing member at first and second filling ports 34 a, 34 b opposite to the first and second filling chambers 22 a, 22 b. This step is typically done by an automated filling system.

The portion of package 10 through which the first and second filling chambers 22 a, 22 b are accessed may be referred to as an access region or a penetrable access region. The access region may include the first and second access regions 34 a, 34 b. The access region may be resealable. The access region may provide a sealed interface with a device that accesses the first and second filling chambers 22 a, 22 b through the access region.

FIG. 2c illustrates a further welding step in which a permanent seal is formed. The permanent seal 38 is formed around an entire periphery of the first and second compartments 20 a, 20 b and the area in which the first and second frangible seal portions 30, 32 are defined adjacent to the first and second compartments 20 a, 20 b. The permanent seal pattern 38 surrounds the first and second compartments 20 a, 20 b and overlaps most of the frangible seal pattern formed in the first welding steps shown FIG. 2a , leaving frangible seals 30 and 32 unchanged. The first and second filling ports 34 a, 34 b at the access regions may be formed prior to filling or as part of filling the package 10, and may be performed prior to or after the second weld step to form the permanent seal 38, however the channels 24 a, 24 b, would typically be sealed after the filling chamber has been used for filling or removing material from the package. In one example, the second weld step to form the permanent seal may also seal closed the first and second filling channels 24 a, 24 b. As such, it may be beneficial to provide the permanent seal in the second welding step after filling the first and second compartments 20 a, 20 b (e.g., filling the first compartment 20 a using the filling methods described above).

Referring now to FIGS. 3a-3f , another example package 100 is shown including a compartment 120, a filling chamber 122, a filling channel 124, first and second layers 126, 128, a frangible seal 130, and a fitment 136. FIGS. 3a-3f illustrate filling steps of a method of filling the package 10. The package 10 includes the first layer 126 having a plurality of features formed therein such that when the first and second layers 126 and 128 are connected together the compartment 120, filling chamber 122, and filling channel 124 are defined. The filling channel 124 provides flow communication between the compartment 120 and the filling chamber 122. FIG. 3a shows the package 100 prior to filling, wherein the compartment 120, filling chamber 122, and filling channel 124 are integrally sealed to provide a hermetically sealed package. The package 100 may be sterilized by, for example, heat, radiation, or other sterilizing methods.

FIG. 3b illustrates the package 100 having a filling device 102 that is engaged with the package 100. The filling device 102 includes a filling tube 104 having a piercing feature at its distal end for piercing the second layer 28 of the package 100. The filling device 102 is engaged with the second layer 28 in a fluid-tight fashion, and defines a access region where the filling tube 104 pierces the second layer 128 to gain access to the filling chamber 122. The filling tube 104 and the access region may be disinfected prior to engagement to further reduce contamination risks for the package 100. In one arrangement, the package 100 and the filling device 102 are disinfected using, for example, hydrogen peroxide.

FIG. 3 c illustrates the filling device 102 starting the process of filling the package 100. The filling channel 124 directs a fluid 106 along an inner surface 127 of the second layer 128. Directing the fluid 106 along the inner surface 127 may reduce jetting, bubbles and foaming of the fluid 106.

FIG. 3d illustrates a subsequent step in the filling process when the package 100 is about half full. The fluid 106 continues to flow along the inner surface 127 of the second layer 128 and avoids jetting and reduces bubbles, foaming and mixing of the fluid 106. A gas content within the package 100 may be evacuated through the filling chamber 122 or through a separate filling chamber and filling channel that is in flow communication with the compartment 120.

FIG. 3e illustrates the compartment 120 completely filled and sealed. A sealing device (not shown) may collapse and thermally seal the filling channel 124. In one arrangement, the filling chamber 122 is squeezed prior to sealing the filling channel 124 to transfer the fluidic content of the filling chamber 122 into the compartment 120. In another arrangement, the fluidic content of the filling chamber 122 is sucked back into the filling device 102 via the filling tube 104 after sealing the filling channel 124.

FIG. 3f shows the package 100 after the filling device 102 is retracted and the filling chamber 122 is trimmed from the package 100. The fitment 36 may be connected to a delivery device, such as one of the syringes shown in the figures. The frangible seal 130 may be ruptured to provide flow communications between the compartment 120 and the fitment 136. The frangible seal 130 may be ruptured by increasing pressure within the compartment 120, for example, by applying a compression force to an exterior of the compartment 120.

Referring now to FIG. 4, another arrangement of a portion of a package 110 a is shown having first and second inserts 150 a, 152 a disposed in the filling chamber 122 a and filling channel 124 a. The first insert 150 a may serve as a seal to enhance a fluid-tight seal between the filling device 102 a and the package 110 a. The second insert 152 a may include an internal channel 154 a and an outlet 155 a configured to direct the fluid 106 a to the compartment 120 a onto an inner surface of the second layer of the package 110 a. In one arrangement, at least one of the first and second inserts 152 a, 152 b includes a low melting temperature material that adheres with the first and second layers of the package 110 a. During the step of sealing the compartment 120 a, the second insert 152 a may melt, collapse, and seal the filling channel 124 a.

Referring now to FIGS. 5a-5d , another example package 210 is shown in use with a delivery device 212 as part of a delivery assembly 200. The delivery device 212 may include a Luer syringe that includes a piston and barrel syringe arrangement with a needle 215 for delivering medication. The delivery device also includes a barrel 213, a plunger 214, and a cap 216. The package 210 may be connected to the delivery device 212 with an aseptic engagement. The delivery device 212 may be removable from the package 210. FIGS. 5a -5 c show the package 210 having a single compartment 220 configured to a beneficial agent or a constituent thereof. The beneficial agent or constituent thereof may have been activated to form a dose that can be drawn into the delivery device 212 via the needle 215. The package 210 may include a body 256 having an opening 258 that receives the delivery device 212 to provide flow communication between the package 210 and the delivery device 212.

The package 210 also includes first and second filling chambers 222 a, 222 b and first and second filling channels 224 a, 224 b that provide flow communication between the compartment 220 and the first and second filling chambers 220 a, 220 b. The package 210 may also include a frangible seal 230 that is openable to provide flow communication between the compartment 220 and the needle 215 of the delivery device 212. FIG. 5b shows the frangible seal 230 closed. FIG. 5 c shows the frangible seal 230 opened.

Similar configurations may be operative with other needle arrangements known in the art including, for example, syringes with catheter, needle with protective soft sheathe, intramuscular (IM) needle, subcutaneous (SQ) needle, intradermal (ID) needle, micro needle, safety needles, retractable needles, irrigation needles, and applicators.

The delivery device 212 may include the cap 216 that provides an aseptic closure to the space between the barrel 213 and plunger 214. The cap 216 may help maintain the delivery device 212 as a sterile syringe assembly without the need of a sterile overwrap. FIG. 5d shows the cap 216 removed with the delivery device 212 filled and removed from the package 210. In at least some arrangements, the package 210 and delivery device 212 may be generally referred to as a package or a package having delivery capability.

Referring now to FIGS. 6a-6c , another example package 310 is shown including first and second compartments 320 a, 320 b, first, second, third and fourth filling chambers 322 a-322 d, and first, second, third and fourth filling channels 324 a-324 d. Package 310 also includes first and second frangible seal portions 330, 332 and a fitment 336. FIG. 6c shows a cross-section view of the filling chambers 322 a-322 d. The filling chambers are integrally sealed between first and second layers 326, 328 of the package 310. The package 310 may be sealed empty or filled with air or gas (e.g., Nitrogen). The package 310 may be made in an aseptic fashion from sterile components. Alternatively, the package 310 may be sterilized after formation using, for example, gamma irradiation or e-beam or autoclave. In one example, at least a portion of the second layer 328 comprises a material that is semi-permeable to gas that allows sterilization of the package 310 using a gas such as ETO. An example of such a semi-permeable material is Tyvek.

FIG. 6b shows the package 310 after filling, sealing, and trimming has occurred. The first, second, third and fourth filling channels 324 a-324 d are sealed closed and a sacrificed portion 321 carrying the first, second, third and fourth filling chambers 322 a-322 d is removed. The fitment 336 may be connected to a delivery device such as a syringe to deliver contents of the first and second compartments 320 a, 320 b.

FIGS. 6d and 6e illustrate methods of filling the package 310. A filling device 302 comprises a plurality of filling tubes 304 a-304 d in the form of hollow needles is shown. The filling tubes 304 a-304 d pierce through the second layer 328 to establish fluid communication with the filling chambers 322 a-322 d. A fluid-tight seal may be formed between the second layer 328 and the filling tubes 304 a-304 d. In one example, a first filling tube 304 a may communicate with a first filling chamber 322 a to deliver a first constituent to the first compartment 320 a via a first filling channel 324 a. A second filling tube 304 b communicates with a second of the filling chambers 322 b to exhaust gases from the first compartment 320 a during filling of the first compartment 320 a with a first constituent.

Vacuum may be applied at the second filling tube 304 b to facilitate the filling process. In some arrangements, counter pressure is applied to the exhaust filling chamber 322 b to inflate the constituent compartment 320 a during filling to maximize its holding volume. Similarly, the first compartment 320 a may be inflated by applying flow resistance in the second filling channel 324 b, the second filling chamber 322 b, the second filling tube 304 b, or elsewhere in the exhaust line. In one arrangement, the first compartment 320 a is inflated to its maximum holding volume by applying a vacuum external to the second filling chamber 322 b. The compartment 320 a may be held in a shaped mold while the vacuum is applied to define the inflated first compartment 320 a shape while applying the vacuum.

The package 310 may be tilted during filling such that the exhaust filling channel 324 b and exhaust filling chamber 322 b are elevated relative to the filling channel 324 a and filling chamber 322 a to allow all gases to exit out of the first compartment 320 a before the constituent reaches the exhaust filling channel 324 b. An artificial gravity field may be applied by centrifuge motion. A detector may be embedded in the filling device 302 or in the package 310, or elsewhere to sense that the first compartment 320 a is adequately filled and to indicate to halt the filling process.

In one arrangement, the package 310 is depressed against the filling device 302 by applying force with a body against the first layer 326. In other arrangements, a surface of the filling device 302 comprises vacuum grooves 303 arranged adjacent to the package 310 and in communication with vacuum ports 305 a, 305 b. The applied vacuum helps hold the package 310 against the filling device 302.

An additional sealing member may be disposed in the filling chambers 322 a-322 d to enhance the aseptic seal between the filling device 302 and the package 310. An environment around the package 310 may not necessarily be aseptic or required to be aseptic because the internal compartments, chambers and channels of the package 310 were previously integrally sealed during the process of forming the package 310. Contamination or foreign particles may be avoided from the filling device 302 and associated filling tubes 304 a-304 d by locally maintaining these objects and the portions of the package 310 to interface with the filling device 302 as clean and disinfected. Dry wiping, wiping with alcohol, UV radiation, infrared radiation, heat, freezing, spraying, puffing, brushing, and local depyrogenation are some of the techniques that may be applied, individually or combined, to prevent foreign particles from being introduced into the compartment 320 a as a result of the filling tubes 304 a-304 d piercing the second layer 328.

The filling channels 324 a-324 d may be designed such that the constituent flows along an inner surface of the second layer 322 within the compartment 320 a, 320 b by moving (e.g., gliding) along the inner surface thereby limiting undesirable jetting and foaming. A nozzle or other insert may be disposed in at least one of the filling chambers 322 a, 322 c and filling channels 324 a, 324 c to enhance a desired flow pattern in the compartments 320 a, 320 b. A valve or other regulator may be disposed in one of the filling chambers 322 a, 322 c and filling channels 324 a, 324 c to control the flow to the compartments 320 a, 320 b. Similar valves or regulators may be positioned in the outlet or exhaust filling chambers 322 b, 322 d and filling channels 324 b, 324 d to help provide flow control.

The arrangement of FIGS. 6d and 6e may provide concurrent filling and exhausting of both of the compartments 320 a, 320 b. The elevated, angled orientation of the package 310 and filling device 302 shown in FIGS. 7a and 7b may help remove gases from the compartments 320 a, 320 b during filling.

The arrangement of FIGS. 6d and 6e may also be useful for lyophilizing a constituent in the compartments 320 a, 320 b. In one example, the first constituent is introduced through the filling chambers 322 a, 322 c, and humidity and pressure in the compartments 320 a, 320 b are controlled through the exhaust filling chambers 322 b, 322 d. Filling of the constituent may be performed in one dose or in multiple smaller doses. Filling using multiple smaller doses may allow for better surface evaporation and also allow for more efficient filling of the compartments 320 a, 320 b with a lyophilized cake. Temperature may be controlled by controlling heat transfer through the first and second layers 326, 328, either by introducing the package in a lyophilizer or a controlled environment chamber, or by locally pumping heat to and/or from the first and second layers 326, 328. Because the package is aseptically sealed, the lyophilization environment may not necessarily be aseptic.

The filling channels 324 a-324 d may be sealed closed by heat welding across all of the filling channels 324 a-324 d as shown in FIG. 6b . The filling channels 324 a-324 d may collapse so that the first layer 326 is joined with the second layer 328 to form a permanent closure. Inserts may be disposed in the filling channels 324 a-324 d to facilitate an improved seal. In one arrangement, the inserts may at least partially melt during heat sealing. In one arrangement, the sealing is achieved by bringing the heating element and a counter surface in contact with opposing sides of the package 310. The filling device 302 may comprise the heating element or the counter surface. In one arrangement, the heating element is embedded into package 310 such as in the first or second layers 326, 328, or therebetween. Once the filling channels 324 a-324 d are sealed, the filling chambers 322 a-322 d are removed as shown in FIG. 6b . Residue of the constituents delivered to the first and second compartments 320 a, 320 b may be evacuated either into the first and second compartments 320 a, 320 b or drawn out of the filling chambers 322 a-322 b and filling channels 324 a-324 d prior to or during the process of sealing closed the filling channels 324 a-324 d.

Referring now to FIGS. 7a-7c , the package 310 may include a backing 356 and outer sealing members 360 a-360 d aligned with each of the filling chambers 322 a-322 d. The sealing members 360 a-360 d seal around the filling tubes 304 a-304 d as they are inserted into the filling chambers 322 a-322 d. The sealing members 360 a-360 d may comprise a semi-rigid polymer or elastomer or a combination thereof. In some arrangements, the second layer 328 may include pre-formed holes that are sealed closed by the sealing members 360 a-360 d and ready to receive the filling tubes 304 a-304 d as the filling tubes are inserted through the sealing members 360 a-360 d.

FIG. 7b illustrates an arrangement wherein the backing 356 includes through-holes 357 a-357 d. The through-holes 357 a-357 d may help align the filling tubes 304 a-304 d with the filling chambers 322 a-322 d. A portion of the backing 356 may remain between the through-holes 357 a-357 d and the second layer 328 to maintain the filling chambers 322 a-322 d sealed closed. The backing 356 may be configured to be pierced and may comprise, for example, a pierceable membrane designed to seal around the intruding filling tubes 304 a-304 d.

FIG. 7c shows a plurality of internal sealing members 362 a-362 d positioned within the filling chambers 322 a-322 d. The internal sealing members 362 a-362 d may provide an additional fluid-tight seal between the filling tubes 304 a-304 d and the package 310 during filling. The internal sealing members 362 a-362 d may also provide improved closure of the filling chambers 322 a-322 d upon removal of the filling device 302. The sealing members 362 a-362 d may be joined in a fluid-tight fashion such as by heat welding to the first or second layer 326, 328. The second layer 328 may include ports or through-holes pre-formed therein for receiving the filling tubes 304 a-304 d.

Referring now to FIGS. 8a-8f , another example package 410 is shown including a compartment 420, first, second and third filling chambers 422 a-422 c, and first, second and third filling channels 424 a-424 c. The package 410 also includes first and second layers 426, 428, a fitment cavity 446, a fitment opening 429 formed in the second layer 428, and a fitment 436 having a flange portion 468, a protrusion 465 having an internal conduit 469, a channel 466, and a knockoff portion 467 (see FIG. 8e ).

The channel 466 of the fitment 436 provides fluid communication with the interior of the compartment 420. The fitment 436 is positioned between the first and second layers 426, 428. The flange portion 464 retains the fitment 436 between the first and second layers 426, 428. The protrusion 465 extends through the fitment opening 429. A fluid-tight seal is provided between the first and second layers 426, 428 and the flange portion 464 and protrusion 465. The protrusion 465 is configured to join with a fluid passageway of a dispensing system, a backing, or other external device. A force may be applied to the flange portion 464 through the first layer 426 when joining the package 410 with an external device. In one arrangement, ultrasonic vibration, combined with axial force, is directed to the flange portion 464 to ultrasonically weld the protrusion 465 to an external device. Other joining methods known in the art may be used to connect the fitment 436 to an external device including, for example, gluing and adhesion.

The channel 466 in the flange portion 464 may allow the constituent to flow from the compartment 420 to an outlet of the fitment 436. A frangible seal 430 may be provided between the compartment 420 and the channel 466.

The knockoff portion 467 may be optionally provided at a distal end of the protrusion 465. The knockoff portion 467 may help maintain the channel 466 aseptically sealed. The knockoff portion 467 may be removed prior to usage of the package 410 or prior to integrating the package 410 with an external device. Alternatively to use of the knockoff portion 467, the fitment 436 may be aseptically sealed with a twist-off closure, a flip-off closure, a plug, a cap, an adhered foil, or a welded foil.

In one example, the first and second filling channels 424 a-424 b may be used to fill the compartment 420 by providing filling and exhausting as described above with previous examples. The first and second filling channels 424 a-424 b may be sealed at the end of the filling process after the compartment 420 is completely filled. A third filling chamber 422 c and third filling channel 424 c may be used at a later stage to establish communication of a device with the content of compartment 420 by accessing (e.g., piercing) the third filling chamber 422 c. The third filling channel 424 c may be permanently sealed at the end of this later stage access of the compartment 420 via the third filling chamber 422 c. In one arrangement, the third filling chamber 422 c may be used to sample the constituent held in the compartment 420 or to measure a property of that constituent or product in the compartment 420. In another example, the third filling chamber 422 c and associated third filling channel 424 c may be used to add a substance such as a third constituent to the compartment 420. In another example, the third filling chamber 422 c and associated third filling channel 424 c may be used to remove a substance from the compartment 420. In a still further example, the third filling chamber 422 c and associated third filling channel 424 c may be used to remove moisture from the compartment 420. Other example packages may include any number of additional filling chambers and filling channels that are used in subsequent steps to access the compartment 420 after the compartment 420 has been filled via the first and second filling chambers 422 a, 422 b and first and second filling channels 424 a, 424 b.

According to one example, third and fourth filling chambers may be used to add a constituent to the compartment 420. This arrangement may be advantageous as the compartment 420 is integrally sealed after filling the compartment 420 with a first constituent, and a second constituent is filled via the third and fourth filling chambers at a later stage, such as on a different filling system or in the field of use by a user. In another example, third and fourth filling chambers and third and fourth filling channels may be used to drive a fluid through the compartment 420 to cause fluid exchange in the compartment 420. In a still further arrangement, a third filling chamber and associated third filling channel may provide injection of dry air or inert gas into the compartment 420, and a fourth filling chamber and associated fourth filling channel may be used to recover moist air from the compartment 420.

In another example, a filling chamber and filling channel may introduce gas to a liquid phase constituent that is sealed within the compartment 420 at an entry point below the surface of the liquid constituent's surface within the compartment 420, and a further filling chamber and associated filling channel may be used to evacuate gas from the compartment 420 at a point above the liquid level of the constituent within the compartment 420. As is evident from these examples, a plurality of filling chambers and filling channels may be used to formulate a constituent in the compartment 420 during or after filling of the compartment and sealing the compartment. The introduction of, for example, light, heat, radiation, vibration, cooling or a combination thereof may be provided through one of the first and second layers 426, 428. A heating element may be implemented in the first and second layers 426, 428. In one example, a heating element is embedded in the second layer 428.

In another example manufacturing process, a plurality of packages 410 are made on a web format as illustrated in FIG. 11, and a plurality of heating elements of neighboring packages 410 on the web may be connected in parallel. In one such arrangement, the heating element is a thin registered conductive layer joined to a nonconductive laminate. In one example, a conductive laminate of the second layer 428 is used as a heating element. Electrodes may be connected to the ends of a large web format comprising a plurality of packages 410 and heat cavities by conducting electric current through the conductive layer. A package having at least one heating element is shown and described with reference to FIGS. 24a -24 c.

FIG. 8f shows semi-permeable wall portion 425 aligned with at least one of the filling chambers 424 a-424 c. The semi-permeable wall portion 425 may provide an access region for insertion of a filling member (e.g., filling tube 104 of FIGS. 3a-3f ) through the second layer 428 and into one of the filling chambers 424 a-424 c.

The package 410 may be accessed to remove material or introduce material from the compartment 420. In one example, the first and second filling chambers 422 a, 422 b are accessed via the semi-permeable wall portion 425 for at least one of removing material (e.g., removing gas or removing a sample of the beneficial agent or constituent thereof) and introducing material (e.g., the beneficial agent or constituent thereof) from the compartment 420 or at least one of the first and second filling chambers 422 a, 422 b.

The forming of package 410 may be completed prior to accessing at least one of the first and second filling chambers 422 a, 422 b to fill or remove content from the compartment 420. The forming of package 410 may occur currently with accessing the package 410. The forming of package 410 may occur concurrently with any one of filling the package 410 and sealing the package 410.

FIG. 9 shows an arrangement of a package 410 a wherein a first compartment 420 a and a second compartment 420 b share a common filling chamber 422 b. FIG. 10 shows another example package 410 b in which each of the compartments 420 a, 420 b of a single package comprise a single filling chamber 422 a, 422 b, respectively, and a single filling channel 424 a, 424 b, respectively. Each of the compartments 420 a, 420 b may include a separate frangible seal portion 430, 432, respectively.

Referring again to FIG. 11, a plurality of first layers of a plurality of packages 310 are formed of a single sheet of web material. The compartments, filling chambers and channels are formed in the first layer. The web advances in a production line to receive the second layer and a fitment. Filling of the compartments 320 a, 320 b in packages 310 may be performed simultaneously for a plurality of the packages 310. In one arrangement, adjacent cavities of separate packages on the web 307 may share a filling chamber 322 a as shown in FIG. 12a . Separate filling channels 324 a and 324 d may provide flow communication between the filling chamber 322 a and separate compartments 320 a, 320 b on adjacent packages 310. Alternatively, the adjacent compartments may be on the same package. In one example, an exhaust filling chamber may communicate with a plurality of compartments. The packages 310 may be arranged in rows 308 and columns 309 on the web 307.

In another example, a joined communication channel or bus may communicate with multiple filling chambers for multiple packages as shown in FIG. 12b . FIG. 12b illustrates an arrangement where a plurality of filling channels 324 a, 324 d associated with adjacent compartments 320 a, 320 b are in communication via a bus channel 305 that provides flow communication between a plurality of (to be formed) packages 310.

FIGS. 13a-13f are flow diagrams showing example methods of creating a filled, sealed package in accordance with the various teachings provided herein. FIG. 13a shows a method 500 a of first forming the package at 501, sealing the package at 502, sterilizing the package at 503, filling the package at 504, and singulating the packages from each other at 505.

FIG. 13b shows a method 500 b of first forming the package at 511, sealing the package at 512, sterilizing the package at 513, singulating the packages from each other at 514, and filling the packages at 515.

FIG. 13c shows an example method 500 c that includes first forming the package at 521, sealing the package at 522, singulating the packages from each other at 523, sterilizing the packages at 524, and filling the packages at 525.

FIG. 13d shows a method 500 d that includes forming a package at 531, sealing the package at 532, joining the packages to a device at 533, sterilizing the package (and the device) at 534, singulating the packages from each other at 535, and filling the packages at 536.

FIG. 13e shows an example method 500 e that includes forming a plurality of packages at 541, sealing the packages at 542, joining the packages to a device at 543, sterilizing the packages at 544, filling the packages at 545, and singulating the packages at 546.

FIG. 13f shows an example method 500 f that includes forming a plurality of packages at 551, sealing the packages to at least one device at 552, singulating the packages at 553, filling the packages at 554, and sterilizing the packages at 555.

FIGS. 14a-14f show another example package 610 in the form of a cartridge. The cartridge includes a barrel 664, a plunger 666, a plunger core 668, and a barrier 670 positioned at a proximal end of the plunger core 668. The package 610 defines a compartment 620 and may be sealed at its distal end with an end seal 665. The plunger 666 and plunger core 668 define first and second filling chambers 622 a, 622 b and first and second filling channels 624 a, 624 b. The barrel 664 may comprise, for example, glass or polymer such as polyethylene, polypropylene, COC, COP, or polycarbonate.

FIG. 14b shows the plunger core 668 positioned within the plunger 666. The plunger core may include a thermoplastic material. The barrier 670 may maintain the package 610 aseptically sealed prior to filling. The barrier 670 may comprise any desired material including, for example, a film, foil, molded plastic or rubber, or a combination thereof. The package 610 may be sterilized using, for example, heat or irradiation.

FIGS. 14c and 14d illustrate the package 610 during filling. A filling device 602 having first and second filling tubes 604 a, 604 b may be connected to the package 610. The filling tube 604 a, 604 b may pierce through the barrier 670 to establish fluid communication with the compartment 620 via the first and second filling chambers 622 a, 622 b and the first and second filling channels 624 a, 624 b. In one arrangement, the filling tube 604 a is used to deliver a drug or other beneficial agent into the compartment 620 and the second filling tube 604 b is used to exhaust or draw air or other gases from the compartment 620 prior to or during filling.

The filling tubes 604 a, 604 b may seal against the barrier 670 to maintain the package 610 aseptically sealed during filling. In one example, the barrier 670 comprises a multilayer foil having at least first and second layers 670 a, 670 b, as illustrated in FIG. 14d . The second layer 670 b may include an elastic material that is stretched to form a sheathe or a sleeve-like seal around the filling tube when the barrier 670 is pierced by the first and second filling tubes 604 a, 604 b (see FIG. 14d ). During filling, a pressure within the filling chambers 622 a, 622 b rises to further tighten the seal around the filling tubes 604 a, 604 b to limit leaking. The first layer of the barrier 670 a may comprise a material that is more rigid or less deformable than the inner elastic layer to help maintain the structure and rigidity of the barrier 670 to inhibit collapsing of the barrier 670 when being pierced by the filling tubes 604 a, 604 b and during filling.

The elastic layer of the barrier 670 (e.g., layer 670 b) may include, for example, EVA, EAA, or PE ionomer or ionomer blend such as Easy Peel. The more rigid layer of the barrier 670 (e.g., layer 670 a) may comprise, for example, aluminum, PET, polyester, nylon, or an oriented film.

In at least one example, the filling tube 604 a, 604 b may comprise a relatively dull piercing end that promotes stretching of the inner elastic layer thereby increasing the sleeve effect of the seal 672 when the barrier 670 is being pierced.

The package 610 may be tilted or arranged at an angle during filling so that the air or gas in the compartment 620, which needs to be evacuated during filling, will more readily travel towards the exhaust filling channel 624 b. The filling device 102 may include a sensor for detecting when the compartment 620 is completely filled. This may be detected by sensing the presence of the liquid or other substance being delivered into compartment 620 by the filling device 102. When the compartment 620 is filled, it may be resealed by deforming the filling channels 624 a, 624 b to form a fluid-tight seal or sealed channels 648 a, 648 b as shown in FIG. 14e . The sealed channels 648 a, 648 b may be formed by pinching the filling channels 624 a, 624 b with heated members to form a heat seal. In other arrangements, plugs or sealing members may be disposed in the filling channels 624 a, 624 b to facilitate sealing. The plugs may have a cross-sectional shape that is smaller than that of the filling channels 624 a, 624 b to allow flow around the plugs and seal against the inner wall of the filling channels 624 a, 624 b as the channels are collapsed. Alternatively, the plugs may comprise at least one through-hole allowing fluid flow to and from the compartment 620 and the path into the compartment 620 is sealed when the filling channels 624 a, 624 b collapse.

The plugs may comprise a rubber material or a low melting point polymer. After sealing the filling channels 624 a, 624 b, the portion of plunger 666 and plunger core 668 that define the filling chambers 622 a, 622 b may be removed as illustrated in FIG. 14f The sealed channels 648 a, 648 b may maintain the package 610 aseptically sealed.

The arrangement of package 610 in a cartridge form may allow a manufacturing method wherein the package 610 can be transferred to a filling station (or filling line or filling site) fully assembled and sterilized, thereby substantially reducing capital equipment and filling operation costs and complexity.

In one example, the plunger 666 and plunger core 668 comprise a common material that provides properties advantageous for sealing the barrel 664 and heat sealing the filling channels 624 a, 624 b. In one example, the filling chambers 622 a, 622 b are merely extensions of the filling channels 624 a, 624 b. The filling device 102 may seal against a wall defining the filling chambers 622 a, 622 b instead of against a barrier 670. In another example, only a single one of the filling chambers 622 a, 622 b is included in the package 610. In another arrangement, more than two filling chambers 622 a, 622 b may be provided with the package 610 for simultaneous or consecutive delivery of several substances to the compartment 620. In one example, only a single filling channel 624 a, 624 b is provided in the device. In other examples, more than two filling channels 624, 624 b are provided such that several substances may be filled simultaneously or consecutively into the compartment 620.

In one arrangement, at least one filling chamber is sealed with a semi-permeable material to allow sterilization of the compartment 620 using sterilization fluid such as, for example, ETO or HPV. In one example, the filling chambers 622 a, 622 b are sealed with a sealing component such as a rubber seal instead of or in addition to the barrier 670. A vacuum system may be used to attach the filling device 102 to the package 610 (e.g., against the barrier 670). The use of vacuum may help prevent leakage between the filling device 602 and the package 610. In one example, the substance (drug) remaining in the plunger 666 and plunger core 668 after sealing the filling channels 624 a, 624 b may be withdrawn by the filling system 602. The package 610 may be maintained under vacuum prior to piercing of the barrier 670 with the filling system 602 to facilitate delivery of the substance (e.g., drug) into the compartment 620.

Referring now to FIGS. 15a-15b , another example package 710 is shown including many of the same or similar features as described above with reference to package 610. The package 710 includes a barrel 764, plunger 766 and plunger core 768. The package 710 may define a compartment 720 and may be sealed at its distal end with an end seal 765. The plunger 766 and plunger core 768 may define first and second filling chambers 722 a, 722 b, first and second filling channels 724 a, 724 b, first and second filling bores 774 a, 774 b, and first and second passageways 775 a, 775 b.

The plunger core 768 may be movable in an axial direction relative to the plunger 766 from a first position wherein the first and second passageways 775 a, 775 b from the filling channels 724 a, 724 b through the filling bores 774 a, 774 b to the compartment 720 are open, to a second position wherein the first and second passageways 775 a, 775 b are sealed closed.

The filling bores 774 a, 774 b may be sized to receive distal tips of the plunger core 768 within which the filling channels 724 a, 724 b are formed. Advancing the plunger core 768 relative to the plunger 766 seals closed fluid flow into the compartment 720. Retracting the plunger core 768 relative to the plunger 766 opens the compartment 720 in flow communication with the filling chambers 722 a, 722 b.

FIG. 15a shows the package 710 prior to filling. FIG. 15b shows the package 710 during filling as filling tubes 704 a, 704 b of a filling system 702 pierce through the barrier 770. The plunger core 768 is in a first position allowing fluid communication between the filling system 702 and the compartment 720. When filling of the compartment 720 is completed, the plunger core 768 is advanced to the second position shown in FIG. 15c . The outer wall of the plunger core 768 seals with the filling bores 774 a, 774 b within the plunger 766 to form the seal. FIG. 15d shows the package 710 after the filling system 702 has been removed and the compartment 720 is filled and aseptically sealed. In this arrangement, the filling channels 724 a, 724 b do not need to be separately sealed using, for example, a heated member that compresses and seals closed the filling channels.

The package 710 may be operable between sealed and unsealed states or conditions using a linear or axial actuation of the plunger 766 relative to the plunger core 768. The seal interface may occur within the barrel 764. Other arrangements are possible in which the seal is formed by relative movement between the plunger 766 and the barrel 764, or between the plunger core 768 and the barrel 764. The seal may be maintained by an interference fit between portions of the plunger 766 and plunger core 768. Once moved into the sealed or second position, the plunger core 768 may be fixed in the sealed position and not be capable of removing to the first or unsealed position relative to the plunger 766.

FIGS. 15b, 15c and 15e show an additional sealing interface between the filling tubes 704 a, 704 b and the package 710. The filling chambers 722 a, 722 b may have a tapered shape that provides contact between the plunger core 768 and distal end portions of the filling tubes 704 a, 704 b to provide a distal seal 771. The distal seal 771 may be a fluid tight seal that is formed in place of or in addition to the seal provided between the barrier 770 and the filling tubes 704 a, 704 b. In at least some embodiments, the distal seal 771 is provided between distal end portions of the filling tubes 704 a, 704 b and the filling channels 724 a, 724 b. The arrangement of the filling tubes 704 a, 704 b shown in FIGS. 15b, 15c and 15e may be referred to as a double sealing or double piercing arrangement for accessing the filling chambers 722 a, 722 b.

Referring now to FIGS. 16a-16f , a package 810 is shown having many of the same or similar features as the packages 610, 710 described above, but is configured to provide sealing of the compartment using a rotational motion.

The package 810 includes a barrel 864, a plunger 866, a plunger core 868, a barrier 870, and an end seal 865. The barrel 864 and plunger 866 may define a compartment 820. The plunger 866 and plunger core 868 may define first and second filling chambers 822 a, 822 b, first and second filling channels 824 a, 824 b, and first and second passageways 875 a, 875 b. The plunger core 868 may rotate relative to plunger 866 to open and close access to the compartment 820 by closing the first and second passageways 875 a, 875 b. In a first position, the plunger core 868 leaves open the first and second passageways 875 a, 875 b from the filling chambers 822 a, 822 b, through the filling channels 824 a, 824 b and into the compartment 820, as shown in FIGS. 16a-16c . The plunger core 868 is rotatable into a closed position shown in FIGS. 16d and 16e in which the fluidic passageway is closed to seal the compartment 820.

FIGS. 16a and 16b show the package 810 in a pre-filled, aseptically sealed configuration. The plunger 866 is in a first position wherein the filling channels 824 a, 824 b provide flow communication between the filling chambers 822 a, 822 b and the compartment 820. FIG. 16c illustrates the barrier 870 being pierced by filling tubes 804 a, 804 b of a filling device 802 to deliver a substance into compartment 820.

FIGS. 16d and 16e show the plunger core 868 in a closed position after filling the compartment 820 is completed. The plunger core 868 has been rotated relative to the plunger 866 so that the plunger core 868 seals the compartment 820. Many other types of rotational seals may be possible for controlling fluid flow from the filling chambers 824 a, 824 b to the compartment 820.

FIG. 16f shows the package 810 having a barrier 870 having a skirt 873 that extends to an outer surface of the barrel 864. The skirt 873 may provide additional sealing of the package 810 that limits contamination from reaching the area between the plunger 866 and inner surfaces of the barrel 864.

FIGS. 17a and 17b show another example package 910 wherein the package is formed using a blow molded and self-contained administration device 976 behind a removable (e.g., twist-off) cover 978. The package 910 includes first and second filling chambers 922 a, 922 b that communicate with a compartment 920 via first and second filling chambers 924 a, 924 b. The package 910 may be blow molded around the administration device 976 with the cover 978 formed integral with the remaining portions of the package 910 with the exception of the administration device 976. The package 910 is one example of a package that is formed in a single molding step wherein the package is aseptically sealed and prepared for filling by a beneficial agent or constituent thereof.

The compartment 920 may have a billows or accordion shape that promotes delivery of the substance, which is later filled into the compartment 920 via the filling chambers 922 a, 922 b and filling channels 924 a, 924 b, upon application of an axial force that compresses the compartment 920 to deliver the substance out through the administration device 976.

The first and second filling chambers 922 a, 922 b and at least portions of the first and second filling channels 924 a, 924 b may be carried by a sacrificial portion 921 that is removed after filling the compartment 920 and sealing the first and second filling channels 924 a, 924 b.

FIGS. 18a-18b show another example package 1010 in the form of a syringe delivery device. The package 1010 includes a barrel 1064 and a plunger 1066 that define a compartment 1020. An adapter 1021 having first and second filling chambers 1022 a, 1022 b and first and second filling channels 1024 a, 1024 b may be attached to the barrel and arranged in flow communication with the compartment 1020 as shown in FIG. 18b . The package 1010 may also include an administration device 1076 enclosed within a removable cover 1078.

The package 1010 may be configured as a disposable syringe. In accordance with one filling method, the plunger 1066 may be retracted prior to filling to create a desired volume of the compartment 1020 within the barrel 1064 to hold a desired amount of dispensable substance (i.e., beneficial agent or constituent thereof). Alternatively, the plunger 1066 may be pushed back by pressure exerted by delivery of the substance into the compartment 1020 via the first and second filling channels 1024 a, 1024 b. In one arrangement, the filling channels are sealed and the filling compartments are removed after filling the compartment 1020. The first and second filling channels 1024 a, 1024 b may be sealed by application of a heated sealing member or any of the other sealing methods described herein. In one example, the first and second filling channels 1024 a, 1024 b communicate with a tip of the syringe structure at the area covered by the cover 1078. In some arrangements, the adapter 1021 is configured to provide an interface between the tip of the syringe (i.e., at a location where the administration device 1076 is secured to the barrel 1064) and the first and second filling channels 1024 a, 1024 b.

FIG. 18d shows the package 1010 of FIGS. 18a-18c having a detent 1065 that retains the plunger 1066 in a fixed axial position during filling of the compartment 1020. The detent may be adjustable to release the plunger 1066 to permit axial movement of the plunger 1066 during delivery of the content via the administration device 1076.

Referring now to FIGS. 19a-19e , a package 1110 is shown in the form of a dual chamber syringe for delivery of a first substance (i.e., a first beneficial agent) and a second substance (i.e., second beneficial agent) consecutively in a single linear operation of a plunger. The package 1110 includes a barrel 1164 having first and second plungers 1166 a, 1166 b positioned therein to define first and second compartments 1120 a, 1120 b. An adapter such as adapter 1021 described above and shown with reference to FIGS. 18a and 18b may be connected in flow communication with one or both of the first and second compartments 1120 a, 1120 b. Filling of the package 1110 may be completed using one of the adapter arrangements described below with reference to FIGS. 20a-20d or 21 a-21 d.

The barrel 1164 may include a bypass channel 1180 that provides a flow path around the first plunger 1166 a when the first plunger 1166 a is in a distal most advanced position within the barrel 1064 as shown in FIGS. 19c and 19d . An administration device 1176 and associated cover 1178 may be positioned at a distal end of the barrel 1164.

The barrel 1164 may include a distal portion 1164 a that is separable from the rest of the barrel 1164 as shown in FIG. 19b . The distal portion 1164 a may be, for example, pre-assembled with the administration device 1176 and associated cover 1178 before connection to the barrel 1164. The distal portion 1164 a may also include a channel 1179 that provides flow communication from the administration device 1176 to the bypass channel 1180 and the compartment 1120.

The first compartment 1120 a is configured to store a first beneficial agent, and is defined in the package 1110 between a distal end of the barrel 1164 and the first plunger 1166. The second compartment 1120 b, for storing a second beneficial agent, is defined in the barrel 1164 between the first plunger 1166 a and the second plunger 1166 b.

The package 1110 may be formed by separately forming the barrel 1164 from a distal portion of the barrel 1164 that includes the bypass channel 1180. The two portions may be formed separately and assembled together in a later step. Alternatively, the bypass channel 1180 could be formed in a single step when forming the remaining portions of the barrel 1164. The portion of the barrel including the bypass channel 1180 may be connected to the remaining portion of the barrel 1164 by any method known in the art including, for example, heat welding, spin welding, ultrasonic welding, RF welding, vibration welding, solvents, glues, adhesives, mechanical interface, press-fit, or via a coupler or tape. Alternatively, the bypass channel 1180 may be molded on an inner wall of the barrel 1164 by applying a reciprocal ridge shape to a core of an injection mold.

FIG. 19a shows the package 1110 after the first and second beneficial agents have been delivered into the first and second compartments 1120 a, 1120 b. FIGS. 19c and 19d show the package 1110 after the second plunger 1166 b has been advanced to advance the first plunger 1166 a to administer the first beneficial agent from the package 1110. The first plunger 1166 a is positioned at a distal most portion of the barrel 1164 so that the bypass channel 1180 extends from a front or distal end of the first plunger 1166 a to a rear or proximal end of the first plunger 1166 a. At this position, the bypass channel 1180 establishes fluid communication between the second compartment 1120 b and the administration device 1176. Further advancement of the second plunger 1166 b toward the distal end of the barrel 1164 will deliver the second beneficial agent through the bypass channel 1180 to the administration device 1176. In one arrangement, the first plunger 1166 a is compressible and its axial length is such that the bypass channel 1180 does not open to the second compartment 1120 b when the first plunger 1166 a reaches the distal end of the barrel 1164 (i.e., when the delivery of the first beneficial agent is completed). A further advancement of the second plunger 1166 b pressurizes the second beneficial agent within the second compartment 1120 b causing the first plunger 1166 a to compress and establish fluid communication through the bypass channel 1180 to the administration device 1176. This multi-stage advancement of the first and second beneficial agents is possible by not opening the bypass channel 1180 until intending to deliver the second beneficial agent further reduces possibility of mixture of the first and second beneficial agents and provides a pronounced sensation to the user when switching from delivering the first beneficial agent to delivering the second beneficial agent.

FIG. 19e shows the package 1110 when the first and second plungers 1166 a, 1166 b are advanced to the distal end of the barrel 1164 and delivery of the first and second beneficial agents has been completed.

Referring now to FIGS. 20a-20d , another example package 1210 in the form of a disposable syringe is described. The package 1210 includes a barrel 1264, first and second plungers 1266 a, 1266 b, a bypass channel 1280, an adapter 1221 having a barrier 1270, first and second compartments 1220 a, 1220 b defined within the barrel 1264, and first and second filling chambers 1222 a, 1222 b and first and second filling channels 1224 a, 1224 b defined within the adapter 1221.

The dual syringe arrangement of the package 1210 may have at least some of the advantages described above with reference to the package 1110 concerning consecutive delivery of first and second beneficial agents. The package 1210 includes an administration device 1276 and a cover 1278 enclosing the administration device 1276. A sealing member 1277 (e.g., a rubber stopper) may be used to seal the administration device 1276. The sealing member 1277 may be positioned between the administration device 1276 and cover 1278 as shown in FIGS. 20b-20d . The package 1210 may include a sterile cap 1216 that maintains a sterile environment within the barrel 1264 at the proximal end of the barrel 1264. The first and second filling channels 1224 a, 1224 b are associated with the distal end of the barrel and may provide access to the first and second compartments 1220 a, 1220 b when the first plunger 1266 a is positioned at a distal end of the barrel 1264 as shown in FIGS. 20b and 20c . The first filling channel 1224 a communicates with the first compartment 1220 a and the first filling chamber 1222 a. The second filling channel 1224 b communicates with the second compartment 1220 b and the second filling chamber 1222 b. The barrier 1270 aseptically seals the first and second filling chambers 1222 a, 1222 b.

FIG. 20c shows a filling device 1202 having first and second filling tubes 1204 a, 1204 b in fluid communication with the first and second filling chambers 1222 a, 1222 b. In one example method of filling the package 1210, the second compartment 1220 b is first filled by delivering a beneficial agent through the second filling tube 1204 b through the second filling chamber 1222 b and second filling channel 1224 b. The second plunger 1266 b may be retracted upon pressure created in the second compartment 1220 b by delivery of the beneficial agent into the second compartment 1220 b. Alternatively, the second plunger 1266 b may be retracted prior to delivering the second beneficial agent into the second compartment 1220 b.

FIG. 20d shows filling of the first compartment 1220 a by the filling system 1202. The first plunger 1266 a is typically positioned so that the bypass channel 1280 is closed prior to delivering the first beneficial agent via the first filling tube 1204 a, first filling chamber 1222 a, and first filling channel 1224 a to the first compartment 1220 a. Delivering the first beneficial agent into the first compartment 1220 a may push back the first plunger 1266 a. As the first plunger 1266 a is pushed back, the second beneficial agent pushes the second plunger 1266 b further back. After the first and second compartments 1220 a, 1220 b are filled, the first and second filling channels 1224 a, 1224 b may be sealed and the adapter 1221 removed in a similar fashion as described above with reference to other embodiments disclosed herein.

The package 1210 may be emptied according to, for example, the methods described above with reference to FIGS. 19a-19e . The content held in package 1210 may be removed for testing or other purposes. The package 1210 may be resealed after being filled, sealed, and later accessed for removing some of the content.

The third and fourth filling channels 1324 c, 1324 d and associated third and fourth filling chambers 1322 c, 1322 d may be connected to a filling device that provides evacuation of gases from the first and second compartments 1320 a, 1320 b. The first and third filling channels 1324 a, 1324 c may be spaced apart axially along barrel 1364, and the second and fourth filling channels 1324 b, 1324 d may be spaced apart axially along the second barrel 1364 to help promote quick and complete filling of the first and second compartments 1320 a, 1320 b.

For filling, the first and second plunger portions 1366 a, 1366 b may be preset in the fill position shown in FIG. 21b , thereby defining the volumes of the first and second compartments 1320 a, 1320 b. The first and second beneficial agents are delivered into the first and second compartments 1320 a, 1320 b via the first and second filling chambers 1322 a, 1322 b and first and second filling channels 1324 a, 1324 b. Gas is evacuated or exhausted from the first and second compartments 1320 a, 1320 b through the second and fourth filling channels 1324 c, 1324 d and the second and fourth filling chambers 1322 c, 1322 d. After the filling of compartments 1320 a, 1320 b is complete, the filling channels 1324 a-1324 d are sealed and the adapters 1321 a, 1321 b are removed as shown in FIGS. 21c and 21d . The channels 1324 a-1324 d may be sealed to form sealed channels 1348 a-1348 d.

FIGS. 22a-22d show another example package 1510 in the form of a vial. The package 1510 includes a vial 1582 sealed with an end seal 1565 to define a compartment 1520. The package 1510 also includes first and second filling chambers 1522 a, 1522 b, first and second filling channels 1524 a, 1524 b, and a barrier 1570 that seals closed the first and second filling chambers 1522 a, 1522 b. The end seal 1565 may be configured as a stopper or septum through which tubes defining the first and second filling channels 1524 a, 1524 b pierce to obtain access to the compartment 1520. The first and second filling channels 1524 a, 1524 b may be associated with a flip top cap of the vial 1582 and pierce through the end seal 1565, and are later removed with the flip top cover when the vial 1582 is opened.

FIG. 22d shows a filling device 1502 having filling tubes 1504 a, 1504 b connected to the package 1510 with the filling tubes 1504 a, 1504 b piercing through the barrier 1570 to obtain access to the first and second filling chambers 1522 a, 1522 b. After delivery of a substance such as a beneficial agent via the filling device 1502 to fill the compartment 1520, the first and second filling channels 1524 a, 1524 b are sealed to form first and second sealed channels 1548 a, 1548 b as shown in FIG. 22c . The filling chambers 1522 a, 1522 b may be removed as shown in FIG. 22 d.

Referring to FIGS. 23a and 23b , another example package 1610 is shown having a similar construction as the package 1510 described above.

In one example, the access regions 1834 a, 1834 b are positioned on a side of the package 1810 opposite the first and second filling chambers 1822 a, 1822 b. The access regions 1834, 1834 b may be resealable, and may be configured to provide a sealed interface between a filling device inserted through the access regions 1834 a, 1834 b into the first and second filling chambers 1822 a, 1822 b as will be described in further detail below.

FIGS. 25 a and 25 b illustrate top and bottom perspective views of the delivery assembly 1800. FIG. 25b shows the access regions 1834 a, 1834 b having been penetrated (e.g., pierced) to gain access to the first and second filling chambers 1822 a, 1822 b as part of filling the compartment 1820.

FIG. 25c shows the first and second filling chambers 1822 a, 1822 b collapsed to remove the contents held in the first and second filling chambers 1822 a, 1822 b during filling. Collapsing the first and second filling chambers 1822 a, 1822 b may direct the content held therein into the compartment 1820 or into the filling device.

FIG. 25d shows the first and second filling channels 1824 a, 1824 b collapsed to seal closed a flow path between the compartment 1820 and the first and second filling chambers 1822 a, 1822 b. The filling channels 1824 a, 1824 b may be sealed closed using, for example, a heating element. The first and second filling channels 1824 a, 1824 b after being sealed may be referred to as first and second sealed channels 1848 a, 1848 b.

FIG. 25 e shows an alternative form of trimming the package 1810 to remove the collapsed first and second filling chambers 1822 a, 1822 b. A pair of punched holes 1861 a, 1861 b are formed in the package 1810 to remove the first and second filling chambers 1822 a, 1822 b. Other types of trimming are shown with reference to, for example, the package 10 discussed with reference to FIGS. 1a-1f and the package 210 shown with reference to FIGS. 5a-5d . The step of trimming may be conducted at a separate location from the filling, collapsing and sealing steps shown with reference to FIGS. 5a-5d . In at least some examples, the trimming step, including punching the holes 1861 a, 1861 b, may create contaminants such as dust that may affect sterility of the filling instruments used to fill, collapse and seal the package 1810.

FIGS. 26a and 26b show additional views of the delivery assembly 1800. FIG. 26b shows a cross-sectional view of the compartment 1820, first filling chamber 1822 a, first filling channel 1824 a, access region 1834 a and a portion of the body 1856 of package 1810. The cross-sectional view of FIG. 26b is included in FIGS. 30a-30e to help illustrate a process or method of filling the package 1810.

FIG. 27 shows a filling station 1890 of an example filling system. The filling station 1890 includes a holding cavity 1891, a cavity vacuum line 1892, a chamber collapsing member 1893, a collapsing member bore 1894, a chamber vacuum line 1895, a heating member 1896, a heating member bore 1897, and a channel recess 1898. The holding cavity 1891 is sized to receive the compartment 1820 of the package 1810. The holding cavity 1891 is connected to the cavity vacuum line 1892 such that a vacuum applied in the cavity vacuum line 1892 holds the compartment 1820 within the holding cavity 1891.

The chamber collapsing member 1893 is aligned with the first filling chamber 1822 a and moves within the collapsing member bore 1894 toward the first filling chamber 1822 a to collapse the first filling chamber 1822 a. The collapsing member bore 1894 may be connected in flow communication with the chamber vacuum line 1895. A vacuum applied in the chamber vacuum line 1895 may help hold the first filling chamber 1822 a within the collapsing member bore 1894. The channel recess 1898 is sized to receive the first filling channel 1824 a. The heating member 1896 moves within the heating member bore 1897 to contact the first filling channel 1824 a positioned within the channel recess 1898 to seal closed the first filling channel 1824 a.

The filling station 1890 is shown having a single chamber collapsing member 1893 and a single heating member 1896 that are arranged to interact with the first filling chamber 1822 a and the first filling channel 1824 a, respectively. The filling station 1890 typically includes another chamber collapsing member and another heating member that are movable within a chamber member bore and heating member bore, respectively, to interact with the second filling chamber 1824 b and second filling channel 1824 b. The same chamber vacuum line 1894 may be in flow communication with both of the collapsing member bores, or a separate vacuum line 1894 may be provided for each collapsing member bore. In some arrangements, a vacuum line may be connected in flow communication with at least one of the heating member bores.

The collapsing member bore 1894 may have an open end that receives the first filling chamber 1822 a. A shape of the collapsing member bore 1894 may helps shape or maintain a shape of the first filling chamber 1822 a during filling. The shape of the first filling chamber 1822 a formed by positioning in the collapsing member bore 1984 may be preferred for receiving a particular filling device (e.g., filling tube 1804 shown and described with reference to FIGS. 28a and 28b ). A filling chamber having an incorrect or deformed shape may be improperly punctured with the filling device.

Other filling station embodiments may be operable without using a chamber collapsing member. The content held within the filling chamber of the package may be removed by other means including, for example, suction applied by the filling tube 1804. Alternatively, the content is maintained within the filling chamber of the package after sealing of the filling channel and may be discarded as part of trimming the package 1810.

The heating member 1896 may have various constructions and provide sealing in different ways. For example, the heating member 1896 may be an impulse sealer operable with a short burst of heat provided by a low energy source using a high conductive heating element.

FIGS. 28a and 28b show an example filling head 1802 as part of a filling system comprising the filling station 1890. The filling head 1802 includes a sheath 1803 having a flexible skirt 1880, an outlet 1881, and an internal sealing surface 1882. The filling head 1802 also includes a filling tube 1804. The filling tube 1804 may have a pointed tip arranged and configured to penetrate through the access region 1834 a of the package 1810 to position the filling tube 1804 within the first filling chamber 1822 a.

The filling head 1802 may also include a carrier base 1883, a decontamination port 1884, a beneficial agent port 1885, and a filling tube support 1886. The filling tube support may support the filling tube 1804. The beneficial agent port 1885 may be arranged in flow communication with the filling tube 1804. The decontamination port 1884 may be connected in flow communication with an exterior of the filling tube 1804, the outlet 1881 and the sealing surface 1882 to flush out the filling head 1802 prior to connecting with the package 1810 (see FIG. 28a ). FIG. 28b shows the filling tube 1804 advanced through the outlet 1881 to a position wherein the filling tube 1804 penetrates into the first filling chamber 1822 a.

The skirt 1880 of the sheath 1803 may flex to permit movement of the carrier base 1883 to advance the filling tube support 1886 and contact with the sealing surface 1882, and advance the filling tube 1804 through the outlet 1881. A beneficial agent or a constituent thereof is advanced from the beneficial agent port 1885 and out through the filling tube 1804.

FIGS. 29a and 29b show another example filling head 1902. The filling head 1902 includes a sheath 1903 and filling tube 1904. The sheath 1903 includes a skirt 1980, an outlet 1981, a sealing surface 1982, and an exit 1905 for the decontamination fluid. The filling head 1902 also includes a carrier base 1983, a decontamination port 1984, a beneficial agent port 1985, a tube support 1986, a valve sealing lip 1987, and a valve seal membrane 1906. A solenoid body 1988 may move a solenoid actuator 1989 to move the valve seal membrane 1906 into and out of contact with the valve sealing lip 1987 to control flow of a beneficial agent or constituent thereof via the beneficial agent port 1985 into the filling tube 1904.

The solenoid actuator 1989 may help maintain a seal between the valve seal membrane 1906 and the valve sealing lip 1987 during delivery of the decontamination fluid via the decontamination port 1984 around the filling tube 1904 and out of the beneficial agent exit 1905 as shown in FIG. 29a . The carrier base 1983 is then advanced relative to the sheath 1903 to move the filling tube 1904 through the outlet 1981 to advance the filling tube 1904 into the first filling chamber 1822 a. The solenoid actuator 1989 is then move the valve seal membrane 1906 out of sealing contact with the valve sealing lip 1987 to permit flow of a beneficial agent or constituent thereof from the beneficial agent port 1985 into the filling tube 1904 as shown in FIG. 29 b.

Many other embodiments are possible for filling heads that may be used in conjunction with a filling station for filling various packages, such as those packages described herein with reference to the attached figures. Another example filling head may include one or more vacuum lines used to remove a sample from the package or to remove content held within the filling chamber of the package prior to or after sealing closed the filling channel after filling the compartment. Other types of filling heads may be operable without use of a decontamination fluid and may use different structure besides the sheath shown with reference to FIGS. 28a-29b . Other features are possible for use with the filling head to maintain sterility of the filling head prior to, during, and after interacting with the package and filling station.

Referring now to FIGS. 30a-30e , an example method of filling the package 1810 of delivery assembly 1800, and preparing the delivery device 1812 for use is shown and described. FIG. 30a shows the package 1810 mounted to the filling station 1890. The compartment 1820 is positioned within the holding cavity 1891. The first filling chamber 1822 a is positioned within the collapsing member bore 1894. The first filling channel 1824 is aligned within the heating member bore 1897. The cavity vacuum line 1892 and chamber vacuum line 1895 may apply a vacuum force that holds the package 1810 in contact with the filling station 1890. The vacuum force applied at the cavity vacuum line 1892 and chamber vacuum line 1895 may maintain a shape or reshape portions of the compartment 1820 and first filling chamber 1822 a.

The filling head 1802 may be prepared for interfacing with the package 1810 by delivering a volume of decontamination fluid via the decontamination port 1884 that passes around the filling tube 1804 and out of the outlet 1881. The filling head 1802 may be aligned with the access region 1834 a. A filling sensor 1807 may be mounted to the filling head 1802 and arranged to align with the first filling channel 1824 a. The filling sensor 1807 may be operable to determine when the compartment 1820 is filled to capacity. In one example, the filling sensor 1807 determines when at least one of the first filling channel 1824 a and compartment 1820 no longer has any gas (e.g., air) positioned therein, which indicates that the compartment 1820 is filled completely with contents (e.g., a beneficial agent or a constituent thereof).

FIG. 30b shows the filling head 1802 contacting the package 1810 with the filling tube 1804 advanced through the access region 1834 a and into the first filling chamber 1822 a. A beneficial agent or a constituent thereof is delivered from the beneficial agent port 1885 through the filling tube 1804, the first filling chamber 1822 a, the first filling channel 1824 a, and into the compartment 1820. The beneficial agent continues to be delivered until the compartment 1820 is completely filled. As described above, the filling head 1802 may include another filling tube and features that provide access to the second filling chamber 1822 b concurrently with accessing the first filling chamber 1822 a. The access via second filling chamber 1822 b may be used to remove gases from the compartment 1820 while delivering the beneficial agent via the first filling chamber 1822 a.

After the compartment 1820 is completely filled as confirmed by the filling sensor 1807, the filling tube 1804 may be retracted as shown in FIG. 30c and the chamber collapsing member 1893 is advanced to collapse the first filling chamber 1822 a. The content within the first filling chamber 1822 a may be moved through the first filling channel 1824 a into the compartment 1820. In other arrangements, the contents held within filling chamber 1822 a may be moved to a different location such as, for example, the filling tube 1804.

FIG. 30d shows the filling tube 1804 further retracted into the original or rest position shown in FIG. 30a . The filling head 1802 may be removed from contact with the package 1810 and prepared for filling a different package. Preparation for filling a different package may include, for example, delivering a volume of decontamination fluid as shown in FIG. 30 a.

FIG. 30d also shows the heating member 1896 advanced into contact with the first filling channel 1824 a. The heating member 1896 may seal closed the first filling channel 1824 a to seal the compartment 1820. In one example, the heating member 1896 is pre-heated before contacting the package 1810.

FIG. 30e shows the package 1810 detached from the filling head 1802 and the filling station 1890. The content of compartment 1820 may be moved into the delivery device 1812. In one example, the content is drawn into the delivery device by retracting the plunger relative to the barrel 1813. The cap 1860 may be removed to permit operation of the plunger.

The frangible seal 1830 (see FIGS. 25a-25e ) may be ruptured or otherwise broken in order to provide fluid communication between the package 1810 and the delivery device 1812. The delivery device 1812 as shown in FIG. 30e may be prepared for use with a patient by moving the content of compartment 1820 into the delivery device 1812 and detaching the package 1810 from the delivery device 1812 to expose an administration member such as, for example, a needle that is attached to the delivery device 1812 at an end opposite the plunger.

Prior to loading the delivery device 1812 with the content of compartment 1820 (as shown in FIG. 30e ) and after sealing the first filling channel 1824 a (as shown in FIG. 30d ), the package 1810 may be trimmed to remove at least a portion thereof. The trimming step may include, for example, removing the first and second filling chambers 1822 a, 1822 b and at least portions of the first and second filling channels 1824 a, 1824 b, or associated sealed channels 1848 a, 1848 b as shown in FIG. 25d . The trimming may include punching the punched holes 1861 a, 1861 b as shown in FIG. 25e . The trimming of package 1810 may be performed at a different location during manufacturing from a location where the filling system and associated filling, collapsing and sealing steps of FIGS. 30a-30d are performed.

The package 1910 includes first and second layers 1926, 1928 that define at least in part a compartment 1920, a plurality of filling chambers 1922 a-1922 d, and a plurality of filling channels 1924 a-1924 d between the first and second layers 1926, 1928. The package 1910 includes a pair of outlet ports 1919 a, 1919 b that are connected in flow communication with the compartment 1920. The filling chambers 1922 a-1922 d and filling channels 1924 a-1924 d may be used to fill the compartment 1920 with content (e.g., a beneficial agent or a constituent thereof), and the outlet ports 1919 a, 1919 b may be used to remove the content. In at least some examples, the package 1910 is resealable after filling the compartment 1920 via the filling chambers 1922 a-1922 d and filling channels 1924 a-1924 d and before removing the content via at least one of the outlet ports 1919 a, 1919 b.

The infusion bag 1910 may provide a variable volume compartment 1920. The compartment 1920 may be provided in a sealed state and completely empty (e.g., in a vacuum state). The compartment 1920 may hold variable amounts of content (e.g., liquid beneficial agent) without needing to concurrently remove gases. Alternatively, the compartment 1920 may include a volume of gas that is removed as the beneficial agent is filled into the compartment 1920.

The filling chambers 1922 a-1922 d may be accessed through access regions 1934 a-1934 d on the second wall 1928 (see FIG. 31b ). Alternatively, the filling chambers 1922 a-1922 d may be accessed along the first wall 1928. The filling chambers 1922 a-1922 d may be deformed (e.g., collapsed) prior to or after filling of the compartment 1920. For example, the filling chambers 1922 a-1922 d may be collapsed as shown in FIG. 31c for purposes of rolling or stacking the package 1910 when storing or shipping the package 1910 prior to filling. The filling chambers 1922 a-1922 d may be restored to their original or filling shape (see FIGS. 31a and 31b ) by applying, for example, a vacuum force to the filling chambers 1922 a-1922 d when positioning in a filling station (e.g., filling station 1890 described above).
